In the course of working digital electronics projects, it’s unlikely that you will have to convert a number between binary and decimal. If you do find that you need to convert binary numbers to decimal[more…]

To give you an idea of how basic gates work, these electronics projects show you how to assemble an AND gate, an OR gate, and an XOR gate using simple DPDT knife switches. In actual practice, gate circuits[more…]

The BASIC Stamp is an electronic microcontroller made by Parallax, a company started by two kids fresh out of high school in 1986. A BASIC Stamp is an essentially complete, self-contained computer system[more…]

A BASIC Stamp is an essentially complete, self-contained computer system for use in electronic circuits. Although you can purchase a BASIC Stamp microcontroller by itself, the easiest way to get into BASIC[more…]

Before you start writing programs to run on a BASIC Stamp to add special effects to your electronics projects, you must first build the circuit(s) that will connect to the I/O pins on the Stamp. Once the[more…]

To tell the BASIC Stamp what you want it to do in your digital electronics project, you must program it. The BASIC Stamp Windows Editor is the software that you use on your computer to create programs[more…]

You can use a BASIC Stamp microcontroller to create some special effects in your digital electronics projects. But first you have to learn how to write programs to control the controller. If you’ve never[more…]

This electronics project begins by connecting 6 LEDs to the breadboard in a BASIC Stamp HomeWork board and then continues by showing the programming necessary to flash all of the LEDs on and off. You can[more…]

When you look at a crystal radio, one of the simplest of all useful electronic circuits, the first thing you’re likely to notice is the large coil. The coil usually consists of 100 turns or more of small-gauge[more…]

A good, long antenna is an electronic component vital to the successful operation of a crystal radio. In general, the longer the antenna, the better. If possible, try make your antenna at least 50′. Longer[more…]

A servo is a special type of motor for use in electronics that is designed to rotate to a particular position and hold that position until told to rotate to a different position. Hobby servos are frequently[more…]

When your electronics projects take you into the realm of programmable circuits, you may find yourself writing some PBASIC code. In PBASIC, you can create names to use as program labels. You can also create[more…]

Programmable circuits in electronics projects require a bit of programming. If your programmable circuit is a BASIC Stamp, you’ll write that code in PBASIC. PBASIC lets you assign a name to an I/O pin.[more…]
